Reading of the function bits
Master
Slave
— Select the program number on which the functions
bits have to be read
— Activate the “Read functions bits” command:
Write at the address 00(h), the value 0400(h)
Byte 0 = 00(h)
Byte 1 = 04(h) (Y00A(h) = 1)
Acknowledgement
Command echo:
— Byte 0 = 00(h)
— Byte 1 = 04(h) (X00A(h) = 1)
Command error code:
— Byte 2 = FF(h)
— Byte 3 = FF(h)
(if command error code = FFFF(h), command is in
progress)
Running “Read functions bits” command
Command finished
Command echo:
— Byte 0 = 00(h)
— Byte 1 = 04(h) (X00A(h) = 1)
Command error code if the command is correctly
carried out:
— Byte 2 = 00(h)
— Byte 3 = 00(h)
OR if an error occurred during the command:
— Byte 2 = 00(h)
— Byte 3 = 04(h) (X01A(h) = 1)
— Wait the end of the command:
command echo = 0400(h) (X00A(h) = 1)
command error code ≠ FFFF(h) (end of command)
— Deactivate the “Read functions bits” command:
Write at the address 00(h) the value 0000(h)
Byte 0 = 00(h)
Byte 1 = 00(h) (Y00A(h) = 0)
— Read the functions bits in the corresponding area
depending on the configuration mode of the slave
The functions bits are dependents of the program number.
A program selection has to be realised before executing command.
The master instrument must always set to zero the command bit. If it is not done, the slave instrument
will not detect the following command on this bit. It has detection on the rising edge (when the bit
state goes from 0 to 1).
